From d5eff1a3412f6d75bf28f423c5015ece8055407a Mon Sep 17 00:00:00 2001 From: Bryan Schumaker Date: Tue, 3 Aug 2010 13:04:00 -0400 Subject: [PATCH] NFS: Fix /proc/mount for legacy binary interface Add a flag so we know if we mounted the NFS server using the legacy binary interface. If we used the legacy interface, then we should not show the mountd options.
